1 Night workers should provide enough vitamin A, because vitamin A can regulate the synthesis of rhodopsin, a retinal photosensitive substance, improve the adaptability of night workers to dim light and prevent visual fatigue. Workers who stay up late are labor-intensive and consume a lot of energy, so we should pay attention to the supplement of high-quality protein. Protein, the best animal, can reach half of protein's total supply. Because animal protein contains essential amino acids, it is beneficial to ensure that workers who stay up late improve their work efficiency and health. Self-care of those who stay up late Living in a modern society with tense rhythm, people who don't stay up late are lucky. Staying up late will disturb the normal rhythm of the body, thus affecting vision, stomach and sleep. So, how should people who often stay up late take care of themselves? People who stay up late are mostly people who do word work or often operate computers. After a hard night in dim light, it is easy to make eye muscles tired and eyesight decline. Dr Li Changping, a nutritionist in charge of nutrition department in Beijing Hospital of Ministry of Health, told reporters that vitamin A and vitamin B have certain effects on preventing visual impairment. Vitamin A can regulate the synthesis of rhodopsin in retina, improve the adaptability of day and night workers to dim light and prevent visual fatigue. Therefore, we should eat more foods rich in vitamin A, such as carrots, leeks and eels, and animal foods rich in vitamin B, such as lean meat, fish and pig liver. In addition, we should properly supplement calories and eat some fruits, vegetables, meat, eggs and other protein foods to supplement physical exertion, but don't eat too much. Dr. Li Changping believes that eating some dried fruits such as peanuts, almonds, cashews and walnuts is rich in minerals such as protein, vitamin B, vitamin E, calcium iron and vegetable oil, while the cholesterol content is very low, which has a special effect on restoring physical fitness. People who stay up late should not only work hard on diet, but also strengthen physical exercise. If you feel lack of energy or want to sleep during staying up late, you should do gymnastics for a while or do some outdoor activities. Because staying up late will take up the time of normal sleep, you may wish to act according to circumstances in supplementary sleep. For example, when you come home from work, you can close your eyes in the car for a while, or arrange a short nap for yourself during your lunch break at work, which can not only restore your strength, but also refresh yourself. Who feels three hours before the night shift? Go for a walk an hour before the night shift. Avoid doing similar or identical things continuously during night shift. It's best to distract yourself. Besides, drinking some tea and chocolate to stimulate the brain is also a wrong choice. In short, whatever you do, you should have a sense of rhythm like that beautiful music-you can do it with ease.
